I am also running regular system menu with Neek2o r96 launched from USBloader GX. All games seem to run perfectly, but if I go to Wii Save Data it immediately freezes. My real NAND system is 4.1U and emuNAND is 4.3U. And after creating a clean NAND build from ModMii, I did move over the shared2 folder from realNAND and the cert.sys file. Maybe something there is not compatible from 4.1 to 4.3 ??
